Abstract
In a heat exchanger, e.g. a radiator for a motor vehicle, the water box (10) and the expansion chamber (11) are made in a single plastic moulding, and are divided by a common wall (12) having at least one orifice for liquid communication therebetween. The expansion chamber tapers from a wider bottom to a narrower top. The narrower top has a filler cap, while the wider bottom is closed by an add-on cover.
